Not that it matters, the country would never be stupid enough to accept it. The rich should pay more, doing the flat tax would either mean higher taxes for the middle class or more debt for the country. Before you idiots start in on me that we would cut spending to pay for, forget about it. I live in the real world and understand we are not going to have massive cuts in government spending, just isn't going to happen.
As a matter of fact, the government is going to take on an even bigger role in all probablity, as truckers migt need subsides to stay trucking, cold weather areas will have to provide subsides for people to heat their homes, more food stamps with the price of food shooting up and who knows what else?
